I bought these headphones to produce electronic music and I'm 100% happy with their sound, they meet my expectations.
Be aware that these are open headphones, so they are quite loud for someone near you.
They're a little uncomfortable to wear, after a while my head starts to hurt a little due to the hard leather strap.
After 6 years some parts are worn out, the little tension rubber straps at the sides which are supposed to keep the headphones in position are now worn out and the headphones are now constantly to big for me. I see no obvious way to exchange them or to fix this.
The ear cushions are filled with a fine black powder which now almost completely disappeared, because if you remove the cushions, e.g. for cleaning, the powder just falls out of the holes.
I filled them with rice (yummi) and it does the job.
Everything else is just fine, the cable seems to be of superiour quality, it never broke.
I would recommend these AKG headphones if you can live with the minor flaws, after all they still do a good job after 6 years almost daily use.
